How to Identify Classes, relations, multiplicity

I am working on creating a UML design for a CaseStudy. I would like to know what is the best approach to identiy class, attributes, operations and relations from a UseCase. Currently i am using Noun phrase approach but i am facing difficulty in identifying the Analysis classes correctly( i am missing few classes ).

I hereby request you to please suggest me best technique used to identiy below

If you follow the use case description and its steps thoroughly. To achieve a scenario in that use case from UI to domain model, you will cover most of the required classes that are to be present for a use case.
